Truck currently has a recall on it due to it going into first gear unexpectedly. Took truck to closest dealership two weeks ago and had the recall service completed. Was told to expect my check engine light to be on for three or four days. When it stayed on a week I called them back to discuss the light still being on. Rescheduled a follow up appointment for April 12. On April 5 and April 7 the truck had the same problem that the recall was supposed to fix. Going approx 50mph when the truck went into first gear with wheel hop and some fish tailing. When this problem occurs the instrument panel will basically go to all zero's and it takes the truck being turned off for the computer to reset and allow truck to drive normally. Just wanted to document here since truck goes back to dealership tomorrow.

I was entering the interstate system by way of "on ramp". went to accelerate to highway speed (65 mph) and my truck began to shutter and loose power. I had to stay on the shoulder of the road to avoid getting hit by a semi truck. It eventually began to run normal.

2012 Ford king ranch 3.5 ecoboost F150 suddenly down shifts during acceleration. It is labored when accelerating, it gets to the 6th gear then suddenly down shifts.this happens when trying to merge on to the highway and also when coming from a complete stop after sitting at a light, then trying to accelerate. It has happened on the highway at 70mph trying to accelerate to 75 mph too. It seems like it loses power.

These trucks have now had 3 different tsb's on them for cam phasers and the timing chain stretching. When is there going to be a recall? tsb's I am referring to are: Tsb 16-0027, tsb 15-0131, and tsb 14-0194. This is completely out of hand. The fix does actually fix the problem with the improved parts, but these vehicles have failed and Ford is either replacing the engine or actually doing the work in the tsb. If a customer is out of warranty, they must pay for the work. This is not what Ford is suppose to be about and is a disservice to their loyal customer base. I have a 2012 F-150 3.5L ecoboost and I will never buy a Ford again unless they address this issue. It is a similar issue to the 3V 5.4L with phasers and the timing chain, which killed my 2004 F-150, so I have been effected by these issues twice now, directly.

The contact stopped the vehicle and waited. Upon being restarted, the vehicle performed normally. The vehicle was taken to L.B. smith Ford Lincoln (1100 market St, lemoyne, pa 17043, (717) 761-6700) where it was diagnosed that a valve and solenoid body needed to be installed. The vehicle was repaired. The manufacturer was made aware of the failure and did not assist. The failure mileage was 55,995.

Immediately following an oil change, my truck began making insanely loud grinding noises. I attempted to drive from knoxville to chattanooga and barely made it to cleveland. My truck stalled, started back up and I coasted into a parking lot. It would not go over 50. I then found a massive puddle of oil underneath where I parked. The truck was taken to jiffy lube.

Code P0016 timing chain failure. Causing car to lose power when accelerating. This happened on expressway when I was turning into a lane to pass a semi in my lane. I had no power to get going in the passing lane and almost got rear ended.also causes truck to jump when fully stopped and foot on break. This is a on going problem.

Vehicle backfired and started shuttering upon acceleration...check engine light came on replaced ignition coil 6. 1000 miles later, same situation cylinder 1&2...replaced those coils and replaced spark plugs. Shuttering lessoned, still backfired on upon strong acceleration. Definitely a safety concern. The backfire does not trigger the engine light to come on...from the research I've done, this seams to be a common problem with the eco boost

2012 F-150 has an eco boost 3.5 L motor that misfires in damp/wet/rainy/cool weather. Motor goes into a misfire mode with no power to drive or accelerate truck. Before the mileage warranty was up, truck was taken to Ford for their "fix". however, the issue has remained from 2012 to current year, 2018, and without Ford fixing this problem will continue for the indefinite future of these motors from Ford. Cannot trust truck to perform when needed and a safety hazard when driving, towing or accelerating when this occurrs.

The contact owns a 2012 Ford F-150. The contact stated that the vehicle lacked engine power when the vehicle was stationary. An independent mechanic inspected the vehicle and found a P0016 error code, which indicated that the timing belt was loose and needed to be replaced. The contact visited the dealer (medford motors, Inc, 105 Wisconsin ave, medford, wi 54451, (715) 748-3700) and the failure was confirmed. The dealer stated that the repair would cost over $3,000 without a recall available. The manufacturer was notified and confirmed what the dealer stated. The failure mileage was 77,000. Consumer stated loss of power.

Engine failure while driving on city street. 85, xxx miles on vehicle. I purchased vehicle new. Engine threw a rod. Oil spilled all over roadway. Research conducted shows this is a common problem with the ecoboost engine due to intercoolers or timing chain issues. Had there been another vehicle behind me, this could have resulted in a crash due to vehicle losing power with no warning.

I have a 2012 F150 it keep locking up on the road. Ford say moisture is getting in the engine. The truck suddenly stop on the road I have almost been hit atleast 10 times. Suburban Ford dealership is blaming me. I have found 330 pages of complaint about this issue. But yet knowbody is doing nothing about it. I am requesting the government to investigate this issue. This is a safety issue I have been narrowly miss by a semi truck my family could have been killed. If the government does not think this vehicles locking up on the road is of concern I dont know what is. The truck sends codes for #1 #3 #5 cylinders have shut down while driving. Then I have had the engine vapor lock up, because the induction is not allowing water in the motor. How many people that have spent their hard earned money on this truck and have had major issues. Who is protecting the public we look to government to help. This vehicle has big issues please help. One of your questions are when did this happen, since I bought the truck. Ford told me not to drive it when it rains or when the humidity is high. $65000 for a truck and I can't drive it when it rains.

My 2012 Ford F-150 is having serious safety issues that are addressed in for tsb's and safety recalls. Upon contacting Ford Motor Company, I was informed that my vehicle did not have the specific VIN number that matched with their cases. My vehicle fits the recall descriptions with make, model, year, and even manufacturing location and has the exact issues that these recalls are about. The first recall is Ford recall 16S19 : unexpected transmission downshift this will cause my vehicle to randomly downshift multiple gears. When it shifts down it also causes the rear tires are lock up and I have lost control momentarily trying to drive at highway speeds. This also causes wear and tear on the drivetrain. Shifting the motor from 5th gear to 1st immediately sends the motor into a dangerous RPM range causing damage. The second recall is Ford tsb 13-6-8: this causes me to lose all indication on my gauges except for RPM' S. I lose indication on my current speed randomly and also on all of my critical engine temperatures and pressures. This also locks the transmission into 5th gear, making it difficult to slow down properly and accelerate from a stop or slow speed. These two issues combine makes the vehicle a danger to drive. I do not feel safe anymore taking this vehicle anywhere and cannot trust it. I have contacted Ford Motor Company both locally and at its headquarters. Their reply is that they have to fix it. I was told to contact the NHTSA for further help from a friend who encountered similar issues with Ford Motor Company. Thank you for your help.

  • 45,000 miles
Vehicle has less than 45000 miles. Has erratic loss of power while accelerating. Evidence of water in the air intake. Research is showing that the ecoboost engine is collecting more water in the intercooler than the engine can consume. Problems increases in southern humid states. This is problem caused by faulty engineering in the 3.5L ecoboost engine and could cause accidents due to unpredictable loss in power. Loss of power is felt while driving on city and highway driving.
